WINDMILL.

SPECIFICATION forming part of Letters Patent No. 237,959, dated February22, 1881.

' Application filed August 30, 1880. (Model) To all whom it may concernBe it known that I, LYMAN CARRIER, of Minooka, in Grundy county, Stateof Illinois, have invented certain Improvements in Windmills, theconstruction and operation of which I will proceed to explain, referencebeing bad to the annexed drawings, making a part of thisspeeification,and theletters thereon,in which- Figure l is a perspectiveview; Fig. 2, vertical elevation of the pump-rod swivel-connection; Fig.3, a side elevation of a portion of the tire around the wheel, showinghow it is tightened; and Fig. 4 a plan View on the top of the hingeconnecting the machine with the tail. Fig. 5 is a plan view of theswivel-connection between the hollow pump-rod and secondary pump-rod.

My invention relates to improvements in windmills; and it consists inthe peculiar construction and arrangement of parts, as hereinafter morefully set forth.

In the drawings, Arepresents the turn-table that supports the workingparts of the mill, which turn-table, in turn, is supported 011 and turnswith the pipe E, which pipe F stands and turns in the step H in theupper part of the tower R. The turn-table A is intended to beconstructed of wood, hard maple being deemed preferable, so that it maysoak and fill full of oil from the cups at the journals of the maincrank-shaft r, which obviates the necessity of oiling these journalsoftener than every three to six months.

The wheel B is constructed on the plan called a solid wheel, with eitherends of the fans held in gains cut diagonally in the circular wood bands6 and p, in which they are held firm, while these bands are bolted andfastened to the radial arms L of the wheel centering in the metal spiderT, which is attached to the crank-shaft 'r. The whole wheel B isencircled at its periphery by a metal tire, a, which is out in one ormore places, and the ends turned up to form outwardly-proj ectingflanges0. (Shown more particularly in Fig. 3.) These flanges c are providedwith holes and a bolt or bolts, 1, to draw the tire up tightly aroundabout the periphery of the wheel B, to tighten it up in case it getsloose or shaky from any cause. The wheel B is attached to thecrank-shaft T, which crank-shaft gives motion to the other machinery.The pitman '12 connects the crank to the walking-beam S at its outerend, while the other end of the walking-beam S is hinged to the uprightpost P, forming its fulcrum, and the pitman 0 attaches the tubularpump-rod D to the walking-beam S at about the center, making a verysimple device for operating the pump-rod D. The walking-beam S isconstructed in two parts for the purpose of allowing the cord j to passdown between them through the length of the hollow pump-rod D, and alsoprevents the walking-beam S from bending oft sidewise at the crank endon account of the wide space between the two halves at the post P.

The wheel B and crank-shaft r are set in the turn-table A, a little toone side of the center of the tubular post F, on which it turns, so thatwhen the wind presses hard against the wheel it has a tendency to turnthe turn-table A and double up the tail E parallel with the wheel B, sothe wheel will stop, being out of the wind. This is accomplished by themanner in which the tail E is hinged to the turntable.

At the rear of the turn-table A, opposite the wheel B, and projectingfrom both the upper and lower corners, are lugs r, Fig. 4, to which thetail is hinged by the pin m, Fig. 1, passing down through the frame toof the tail and the lugs 9",about central with the turn -table,forming ahinge at that place, upon which the tail E swings. The tail E is held inproper position by means of the weight 01 on the lever 02,

in connection with the levers w, 00, z, and to.

When the Weight is raised up the tail willfold up to be parallel withthe wheel B, on account of the operation of the system of levers justnamed. This weight may be placed along on the lever a at any place toregulate the amount of power necessary to fold the tail. When the windblows too hard the wheel B, being one side of the center, will turnaround, so as to bring the tail flat against the wind, the result ofwhich will be to fold the tail up parallel with the wheel and hold itthere until the wind subsides, when the weight 61 will bring the tailback again at about rightangles with the wheel, as shown in Fig. 1.

The cord passes through the pump-rod D its entire length over thehalf-circular walking-beam i on the upperend of the postP, and beingattached at its upper end to the lever n and at its lower end to thebucket 7;. It is intended that this bucket It shall fill with theoverflow of water from a trough, and when full will, by its weight,raise the lever a and fold the tail up with the wheel in the mannerdescribed, to prevent the pump from running any longer. This bucketk isprovided with a small hole in its bottom to let the water out verygradually, so as to unfold the tail when necessary to set the wheeltoward the wind and cause it to run again.

In order to allow the mill to turn without injury to the pump-rod D, aswivel, S, is provided at its lower end, as shown in Figs. 2 and 5, thelower end of the hollow pump-rod being inserted in the cylinder S andturning therein. To the back face of the hollow cylinder S are securedthe rectangular hollow pieces t t, in which are inserted the split endsof the secondary wooden pump-rod g, by nieansof which swivel S thetubular rod 1) is jointed to a secondary wooden pump rod, g, whicharrangement permits the pump-rod D to turn with the mill.

The weight (I, it will be observed, acts as a governor to regulate thespeed of the mill, causing it to face the wind at any angle or positionaccording to the velocity of the wind.

I am aware that strengthening-bands have heretofore been applied tocylinders, and I therefore lay no claim to such invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is as follows, to wit:

1. The combination, with the wheel B, composed of the concentric bands 0h, provided with gains, fans a n inserted therein, central spider T, andradial arms L, of the transversely-cut tire a, provided with the flanges0 and headed bolts 1, provided with nuts on their screw threaded ends,substantially as described, and for the purpose set forth.

2. The combination, with the turn-table A, centrally pivoted in thetower by means of the pipe F, of the wheel 13, having the bearings ofits crank-shaft upon the side of the turn-table, hollow pump-rod D,walking-beam S, circular lever 1 cord j, bucket is, provided with anorifice in its bottom, lever 11, provided with the adjustable weight d,and pivoted tail E, connected with the lever a, substantially as de'scribed, and for the purpose set forth.

3. The combination, with the hollow pumprod D, of the hollow cylinder S,rectangular hollow pieces t t, secured thereto, and secondary woodenpump-rod g, having a divided upper end, substantially as described, andfor the purpose set forth.
